Non-linear analytical model for a multi-v-shape IPM with concentrated winding

This paper presents a non-linear analytical model of a multi-V-shape Interior Permanent Magnet (IPM) motor with non-overlapping concentrated winding. The model relies on Maxwell equations to compute the flux density in the different parts of the motor. This article proposes a saturated analytical model of the stator and the rotor. The analytical model is used to calculate the average torque, the power factor and the voltage of the motor. It is compared to 2D Finite Element Analysis (FEA) and shows very good results. The developed model is 5 times faster than the FEA thus, it can be used in optimization procedures.
